Help on Transilluminators

[Javier Quintero Vazquez]

Hi.
I need information about the correct selection of a transilluminator, the 
main use will be for visulization of agarose DNA gels stained with 
ethidium bromide.
There are three types of wavelength: 365nm, 300nm and 254nm. Wich one 
is the more appropiate to the above mentioned use ?, Its really 
advantageous to have two or three waves?, would you recommend any 
concrete machine. 
 
Thanks in advance
